Arris Touchstone TM822G DOCSIS 3.0 8x4 Ultra-High Speed Telephony Modem

The Arris TM822G is the same as TM822A, noting that the G series is made for Comcast, while the Arris A series is made for Charter. This model is also an upgrade to the TM722G model, which has top speeds of only 160Mbps and has just one RF channel to assist in download instead of the two that TM822G has. This modem has two phone ports for telephony service, but check with your cable provider before purchasing as these models are made strictly for Comcast rentals.
